In underground mines, it is common for duct-fan auxiliary ventilation to extend over hundreds, in some cases thousands of metres. Typically, they are push systems made of either a single or twin vent line with one or two head fans in series, while some systems also use Booster Fans to supply the additional pressure to maintain the airflow.

The excavation of tunnels and mining roadways requires auxiliary ventilation systems to dilute the noxious gases from blasting and diesel engines and provide a safe environment for workers.

With increasing mine depth there is a subsequent increase in the airflow demand and system pressure [4].These pressure demands become a concern when surface extraction fans can no longer supply the required suction pressure which ultimately restrains mine expansion [4].Therefore, the use of smaller underground auxiliary fans is commonplace in deep-level …

AMV – Auxiliary Mine Ventilation Fan. Auxiliary Mine Fans are integral & symbiotic units in handling the main air stream of the working districts of the mine. They operate with the main mine fan thus boosting the pressure of ventilation air passing through it. Such fans are extensively used in underground mining where inflammable and ...

Basic ventilation system underground where D is a ventilation door or airlock, R is a mine regulator and 1, 2, 3 are working places with a surface exhaust fan.
